What is a VPN?

VPN (Virtual Private Network) allows us to connect to the network through a secure, private tunnel. Security is ensured by the variable IP of our computer and really strong data encryption. Thanks to a VPN, we can anonymously browse the Internet and choose the location that the servers will see. It is a solution that not only allows us to safely use the Internet, but also opens up new pages that are not normally available in our country. (source: What is a VPN? - topvpn.pl)

What is the standard for connecting to the network

As you use the web on a daily basis, many companies collect information about the pages you visit and analyze your web traffic. Clicks, activity time and shopping habits are taken under the microscope. Such data is used to optimize advertisements, customize services to the needs of customers and are often transferred between companies. It is a web site a form of user trackingin the era of modern analyzing algorithms, can be a truly perfect mine of knowledge, both about the user and his private life.

This type of data is stored on servers with an assigned IP address, i.e. your personal identifier, which clearly indicates the address and the user. Thanks to this mechanism, each time you connect to any site, it is able to determine who you are and combine this data with those collected earlier.

How does a VPN work?

When you use a VPN, the traffic you generate on the network goes through additional remote server, which allows changing your IP address, and all traffic between your computer and that server is encrypted. The whole connection takes place through a special private tunnel, which is a barrier for potential voyeurs. (source:What is a VPN? 8 tips on how to choose a VPN to be safe on the Internet

For example, if we connect to a server from the Czech Republic using a VPN, all traffic will be directed to this server and will be encrypted there. Only later will the VPN reconnect to the site we wanted to visit. The website we are on can no longer see the user, but the remote server through which the connection has passed.

What does a VPN protect against?

By far the most important reason to use a VPN is privacy of our data. Thanks to the use of such a solution, even an internet service provider will not be able to monitor your behavior on the Internet.

What can the supplier do with this data? Really a lot, because the Polish law provides for the need to issue information from the last 12 months to all entities authorized to do so. On the one hand, such behavior should strengthen consumer protection and protect against fraudsters, but on the other hand, it can be used for unauthorized transfer of data or leakage of data in the event of taking over company servers.

In this case, by far the most dangerous is connecting to unencrypted pages. When we do not see a green padlock on the website, all information that we transmit can be directly saved along with our IP. These include our messages, uploaded photos, contacts, and more. The situation is slightly better on encrypted websites. Here you can no longer get such details, but the provider still shows the pages visited, the time spent on them and the size of the files downloaded.

A VPN also protects us in situations when we use public networks or networks located in a workplace or school. In a situation where we are connected to many people in the public network, there is a really good chance that someone will want to steal our private data, such as passwords or logins to portals. From a thief's point of view, this can be invaluable information. When you use a VPN, yours visible to others the traffic is limited to the information that this is how you connect to the network.

The undoubted advantage of a VPN is also the ability to bypass all local blocks. With the help of tunneling, we can watch series and programs in Poland that would not normally be available to us. It is an ideal way to access Internet resources that we would be waiting for a long time or would never be available to us.

Summation

How could you find out A VPN is a reliable solution for ensuring anonymity in the network and guarantees the security of information transmission. In addition, it allows access to sites and entertainment from around the world. Investing in a good VPN will certainly not be a bad solution for any conscious Internet user.
